The present invention relates to a novel and construction illustrated inthe accompanying suitable device for passing cables and other drawingswherein: suitable electrical current conducting means Fig. 1 shows aroof standard in section in through roofs of any suitable type. Sucharwhich the conducting members are separate fr? rangements may bereferred to as roof inserts, W t 1n the SeetiOIl Shown in g- 2 ingstandards. In the known forms of conhe ecnductlng members are formed bycastruction they consist of a roof stand pipe and bleS O cab e-likebodies. a socket seated therein and overlapping the e head of thestandard consists in the end of the pipe, on which a socket there, iseX- f nner of the protecting hood a and tremely unsatisfactory asregards penetration YES SOCKet e latter is provided with of water andmoisture, prevention of short holhs {Oh the l g of the Currentconduccircuits and the occurrence of fires both in the tors 5 and With ss for the reception of a d i it lf d i b ildi current distributor f towhich are connected The present invention eliminates these dispp y leads6 p g r g the pen.

V closure plate t.

Instead of the pipe it, which extends through out, there is provided atthe upper part a short screw threaded pipe h secured in the socket b bymeans of the nut 71, the two conical bodies 0 and the pressure ring w. Afurther reduced screw threaded sleeve 19 presses the correspondinglyreduced portion of the pipe k which is preferably slit, against thecovering of the cable which is secured in this manner. At the same timethe conductor wires are relieved of pull. The screw connection at thelower portion of the pipe a is effected in the manner shown in Fig. 1.As however the pipe h is omitted there is again provided a screwthreaded pipe /c on which is fitted the conical nut 1 the lock nut 74and a By. tightening the nut the pressure ring it is pressed by thconical portion of the nuts rand 6 against the inner wall of the pipe(Z. The closure disc t is also adapted to take up the axial thrust ofthe stand pipe (Z. This is secured by an angle iron u and'a tubular bello to the upper side of a roof beam of a roof (Z on the upper sidethereof. The supporting plate 6 engages underthe edge 8 of the standpipe 65 and at the same time is connected by a projection with acorresponding slot in the angle iron u. The inner supporting ring wprevents the standpipe d from being deformed or crushed when tightlydrawing up the tubular bell 'v. For increasing the. fireproofness thefree space of the pipe (Z may be fitted with a fireproof mass forexample kieselguhr 2. It will be understood that modifications may bemade in the details of construction without departing from the scope ofthe invention.

.Vhat I claim is 1'. Means for supporting electrical cables with-respectto roofs and the like including a bracket carried by a roof element, astand pipe carried by the bracket and rising above thereof, a hoodresting on and having seal connection with the upper end of the standpipe, a conductor pipe for the electrical cables extendinglongitudinally of the stand pipe and into the hood, means on the upperendof the conductor pipe to seal the same, means carried by theconductor pipe to interiock the conductor pipe and hood against relativemovement in one direction, means on the lower end of the conductor pipewhereby the latter may be connected to a junction box,

and means cooperating with the conductor 7 pipe and with the stand pipeto seal the lower end of the latter.

2. Means for supporting electrical cables with respect to roofs and thelike including a bracket carried by a root element, a conductor pipe'removably connected to a juncture box and extending through and abovethe bracket, a hood interlocked with the upper end of the conductorwhereby the upper 'end of the conductor pipe may be sealed within thehood, a stand pipe pipe, means encircling the conductor pipe andsupported by the bracket, the upper end of the stand pipe having sealconnection with and supporting the hood, sealing means for the lower endof the stand pipe, said sealing means being carried by the conductorpipe, and means for insuring cooperation of the sealing means with theconductor pipe to seal the interior of the latter at the lower endagainst the elements.

In testimony whereof I afiix my signature.
